I. INTRODUCTION
A. SYSTEM OVERVIEW
ThePT-6IFAPentium Pro PCI Local Bus system board is an ATX form-factor
system board. It is designed based on the Intel 82440FX PCIset system chipset and
Winbond I/O chipset. It built-in two channel PIO and Bus Master Enhanced PCI IDE
ports, one Floppy Disk control port, two high speed Serial ports (UARTs) and one
multimode Parallel port and also supports PS/2 mouse, IR and USB ports. It is designed
to fit a high performance, Pentium Pro Processor 150 MHz up to 266 MHz based
solution for high-end and true GREEN-PC computer systems.
The Pentium Pro Processor is a 64-bit processor with RISC technology, which offers
several key features such as built-in 256KB/512KB L2 cache, 12-stage superpipeline
architecture, out of order execution .... etc, in order to optimize its capabilities and
performances, the Pentium Pro Processors require 32-bit Operating Systems (such
Windows NT and OS/2) and applications.
This system board supports the Peripheral Component Interconnect (PCI) Local Bus
standard (PCI Spec. Rev. 2.1 compliant). It not only breaks through the I/O bottlenecks
of the traditional ISA main board, but also provides the performance needs for
networking and multi-user environments.
A. FEATURES
The PT-6IFA system board contains the following features:
Supports wide range Pentium Pro family CPUs from 150 MHZ through 266
MHz , fully IBM PC/AT compatible system board with ISA Bus and PCI Local
Bus.
Built-in 3 set voltage regulator circuits to support all low-voltage components
include CPU, chipset ..., so that no VRM (Voltage Regulator Module) is needed.
DRAM Memory : Supports fast page mode (FPM), Extended Data Out (EDO)
and Burst Extended Data Out (BEDO) memory. Supports

PT-6IFA SYSTEM BOARD HARDWARE SETUP

I. HARDWARE SETUP
A. UNPACKING
The system board package should contain the following parts :
The PT-6IFA system board.
OPERATION MANUAL.
Cable set for IDE and I/O device.
A. HARDWARE CONFIGURATION
Before the system board is ready to operate, the hardware must be configured to allow
for various functions within the system. To configure the PT-6IFA system board is a
simple task, only a few jumpers, connectors, cables and sockets needs to be selected and
installed. (For the detailed locations of each component please refer to page 3-1 "system
board layout" figure )
1. DRAM INSTALLATION
The PT-6IFA system board will support four banks main memory on board (bank0 :
SIMM1, SIMM2. bank1 : SIMM3, SIMM4. bank2 : SIMM5, SIMM6), each bank could
be single-sided or double-sided, 8MB up to 768 MB of local memory can be attained. It
supports three types of DRAM memory either standard fast page mode (FPM),
Extended Data Out (EDO) or Burst Extended Data Out (BEDO) memory. (Both
Symmetrical and Asymmetrical DRAM addressing are supported.)
Bank can be populated in any order (bank 0 does not have to be populated before bank
1). Within any given bank, two SIMMs must be same size. Among the two banks,
SIMMs' densities could be mixed in any order. EDO, FPM and BEDO DRAMs could
be mixed between Banks, a given SIMM must contain only one type of DRAM. When
DRAM types are mixed, each SIMM runs optimized for that particular type of DRAM.
The speed of FPM DRAMs must be used 70ns or faster than 70ns, the speed of EDO
DRAMs and BEDO DRAMs must be used 60ns or faster than 60ns.
PT-6IFA SYSTEM BOARD HARDWARE SETUP
2
There is no jumper needed for DRAM configuration, DRAMs' type and size will be
detected by system BIOS automatically.
In DRAM memory subsystem, ECC and Parity can be checked on the DRAM interface
(Functions selected by BIOS via CMOS setup, please refer to Chapter 5, the defult
status is parity selected.) All SIMMs and DIMM must be populated with parity bit to
implement ECC or Parity functions.
ECC is an optional data integrity feature provided by the system. This feature provides
single-bit error correction, multiple-bit error detection, and detection of all errors
confined to single nibble for DRAM memory subsystem.
The SIMMs' operating voltage are :
SIMM1 - SIMM6 : + 5V DC
The usable DRAM modules are : (Note : S = Single-sided , D = Double-sided)
SIMMs : 1MBx32(36)-S ( 4MB) ,
2MBx32(36)-D ( 8MB) ,
4MBx32(36)-S ( 16MB) ,
8MBx32(36)-D ( 32MB) ,
16MBx32(36)-S ( 64MB) ,
32MBx32(36)-D (128MB) .
The following table is an example for DRAM memory installation, it contains several
modules combination, but not all combination.

1. JUMPERS
A jumper is two, three or more pins which may or may not be covered by a plastic
connector plug (mini-jumper). A jumper is used to select different system options.
Please make sure all jumpers at correct position before this system board used.
(A) JP1 CPU operating voltage selection
Different Pentium Pro processors may require different operating voltages (VccP).
Current processors (marked "Pentium Pro") support VID and will automatically
adjust the output of voltage regulator so that no jumper setting are needed (leave
these jumpers open in this case). Some older processors without VID support
require manual voltage ID setting. The following table is used for those older
processors only.

A. GETTING STARTED
When the system is first powered on or reset, the BIOS will enter the Power-On Self
Test routines ( POST : Display a copyright message on the screen followed by a
diagnostics and initialization procedure.) (If an EGA or VGA card is installed, the
copyright message of the video card maybe displayed on the screen first.) The BIOS
will indicate any error or malfunction by a series of beeps or display the error message
on screen.
Normally, the simulate figure 5-1 will display on the screen when the system is powered
on.

NORMAL : For IDE hard disks size smaller then 528MB.
LBA : For IDE hard disks size larger then 528MB and up to 8.4GB (Giga
Bytes) that use Logic Block Addressing (LBA) mode.
Large : For IDE hard disks size larger then 528MB that do not use LBA mode.
Large mode is a new specifition which may not be fully supported by
all operation systems. Now it can only be used with the MS-DOS and is
very uncommon.
Auto : Auto is a new technology, you can select "Auto" under TYPE and
Mode fields. This will enable automatic detection of your IDE driver during
bootup.
(Note :Some OSes (like SCO-UNIX) must use "NORMAL" for installation.)
